Abstract

The invention discloses a high-filling master batch composition for food and medicine packaging polyolefin. A carrier resin is a polyolefin resin which comprises a metallocene polyolefin resin. The composition also comprises filler and a functional aid which comprises a dispersing agent, a coupling agent, a lubricating agent and a stabilizing agent, or a mixture of two of the dispersing agent, the coupling agent, the lubricating agent and the stabilizing agent. The metallocene polyolefin resin is introduced and is used as the carrier resin, and the conventional functional aid and the filler are added, so the obtained filling master batch composition is high in whiteness, dispersibility, melt fluidity, and processability, and good in normal-temperature and low-temperature impact resistance performance, and a product meets the contact and control requirements of food and medicines, can be used as the filling master batch special for the packaging plastic of the foods and medicines, and has the function of coloring master batch.

Description

technical field [0001] The present invention relates to a fine chemical color masterbatch and filler masterbatch formula composition, specifically, the present invention relates to a filler masterbatch composition for food and drug packaging polyolefin, especially suitable for filling polypropylene materials for food and drug packaging, high filling Density polyethylene material. Background technique [0002] Filler masterbatch refers to the pellets obtained by mixing various additives, fillers and a small amount of carrier resin in the process of plastic processing and molding. It consists of three parts: carrier resin, filler and various additives. Performance and cost depend primarily on the carrier resin. The filler masterbatch can be obtained by mixing fillers, carrier resins and functional additives and extruding pellets. It is a kind of regular geometric figure (such as cylindrical, ellipsoid) particles. The main component of filler masterbatch is filler, which is ...
